Pilomatricoma

討論

The lesion was removed and the diagnosis was pilomatricoma (calcifying epithelioma of Malherbe), with the presence of island of epithelioid cells, shadow cells and calcifications. This benign lesion originates from the hair follicle matrix. It represents 0.12% of all cutaneous lesions but is not infrequent in children, as the vast majority occurs in patients under the age of 21. The location of predilection is the head and neck region. Treatment is by surgical excision with low recurrence rate. Some cases imaged with FDG have been reported in adults but not yet in children.
